PoE Cast On Critical Strike, Shadow, Chaining builds

Hi, I was checking all the replica items to see if I could find a fun new item to build around and I saw the new replica Duskdawn. It's identical to the original, but instead of criticial chance for spells it has base crit chance, bringing it to a respectable \~10%, with 1.25 APS. I was building around it on PoB, using a trickster and stacking block, and ended up with something interesting without using insane gear or cluster jewels: 4.4k Life, but... 59/17 attack/spell block Phase Acrobatics The new Arctic Armour that freezes everyone that hits you, for 0% mana reserved
